Sharing your own company’s information is a big no-no, and probably a breach of contract, both at the interview stage, and also if you decide to join the other company. Don’t even share that your current company is working on a competing product. Your potential new employer knows who you work for and will not disclose competitively relevant information, so ask anything you want. Even if it wasn’t an open source product.

It would only be unethical if you have no intention of joining the new company and are only interviewing to gain information for your current employer.

Thank you for the clarity on not sharing my company's own information. That settles that.

> Your potential new employer knows who you work for and will not disclose competitively relevant information, so ask anything you want.

One small hitch is that my potential new employer doesn't know that my current company is going to enter the same space, and may have already shared competitively relevant information -- I'm not sure what qualifies as competitively relevant, but we had a talk.

But in any case, I think the tack I take is that I should trust the potential new employer not to share anything they wouldn't be comfortable sharing regardless of my employer -- does that sound right?
